| description | The invention provides a forming method for integrally-forged multiple nozzles of a large-scale integrated connecting pipe section, which comprises the following steps: preparing a cylindrical intermediate blank, and arranging an annular convex shoulder for forming the nozzles on the outer wall of the intermediate blank; sleeving two annular ring cutters on the blank on two sides of the annular convex shoulder, pushing the ring cutters to move towards the annular convex shoulder, and cutting edges of the ring cutters into the root of the annular convex shoulder; the annular convex shoulder is subjected to material distribution, and a plurality of pipe nozzle blanks are obtained; pre-forging the pipe nozzle blank by using a pre-forming die to obtain a pipe nozzle intermediate blank; and carrying out finish forging on the pipe nozzle intermediate blank by utilizing the finish forming die to obtain the pipe nozzle. The material utilization rate and the forging efficiency can be improved, and the pipe nozzle with |
